Unidentified Developer: Digital Signature

While regular Aquamacs releases are digitally signed, the nightly
builds are not (for security reasons). This means that you may
get an error message when first starting up a freshly downloaded
Aquamacs: "Aquamacs can't be opened because it is from an
unidentified developer.".

To work around this, just double-click on the app in Finder while
holding the Control button. You only need to do this once.

You can verify the source of your download by making sure that it
comes from "aquamacs.org", the official internet domain of the
Aquamacs project.
